Wood Identification
Anatomic Description Of Wood
Wood diffuse porous. Vessels in radial multiples of 2 to 4. Tangential diameter of vessel lumina 100 to 150 micras (small). Vessels per mm2 more than 20 (very abundant). Simple perforation plates. Vessel-ray pits coarse throughout the ray cell. Vessel-ray pits Axial parenchyma in continuous tangential lines or fine bands. Non-crystals in axial parenchyma cells. 5 to 8 cells per parenchyma strand. Axial parenchyma in narrow bands on lines up to 3 cells wide. Axial parenchyma bands over 4 per mm. Rays more than 10 per mm (abundant). Rays non-storied. Rays 1 to 4 seriate. Silica bodies in the ray cells. Heterogeneous rays and/or multiseriate heterogeneous rays. Non-septate fibers. Fibers with simple to minutely bordered pits.
